Two boys were stabbed Saturday night during a fight that broke out in Vancouver when people apparently tried to crash a party.

Police received several calls about 11:30 p.m. about a fight at the Luepke Center on East McLoughlin Boulevard. One caller said 40 people were involved. Another caller said a knife, bat and bottles were being used. A third caller reported seeing only a belt.

Vancouver police found no weapons or evidence of a fight. Awhile later, though, police were called to a Vancouver hospital, where a 17-year-old boy was being treated for a single stab wound to his back. At the same time, a second call came from another hospital, where another teenage boy was treated for a similar injury. Neither injury was life-threatening.

Police think both stabbings occurred during the fight at the party. The victims' names are being withheld and an investigation continues.

"At this point we don't have victims who are cooperating," said Deanna Watkins, an officer with the Vancouver Police Department. "We have no suspects and no leads."
